BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a radar reflective vehicle breakdownwarning sign, and particularly to a radar reflective vehicle breakdownwarning sign that a driver may use to display warning and failuremessages without having to get off the vehicle for achieving the effectof preventing collision of autonomous and human-driven vehiclesapproaching from behind and protecting the safety of the driver.

2. Description of Related Art

When a vehicle breaks down on the road, the driver would usually parkthe vehicle on a side of the road, get off the vehicle, take out avehicle breakdown warning sign from a rear trunk and put it at anappropriate distance from the rear of the vehicle for alerting vehiclesapproaching from behind to avoid collision. However, it is risky for thedriver to get off the vehicle if this happens on a highway or anexpressway, where vehicles move at high speed.

With the advance of technology, some modern-day vehicles are equippedwith road condition detecting devices, and for some vehicle brands theyare included in the standard equipment. A road condition detectingdevice may detect road conditions ahead when a vehicle is moving andalert the driver when the vehicle is approaching an object within acertain distance to achieve the purpose of safe driving. A radardetecting device, however, is usually more sensitive to moving objectsthan stationary ones. Therefore, when a vehicle breaks down and isstationary ahead, even if a vehicle breakdown warning sign is placedbehind the broken vehicle, a car accident may still happen since theradar detecting device may not be able to detect it and the driver mayalso fail to notice it if he/she relies too much on the radar detectingdevice. In view of this, after laborious research and experiments, theapplicant has devised a radar reflective vehicle breakdown warning signthat a driver may use to display warning and failure messages withouthaving to get off the vehicle for achieving the effect of preventingcollision of autonomous and human-driven vehicles approaching frombehind and protecting the safety of the driver.

SUMMARY OF THE INVENTION

It is a primary objective of the present invention to provide a radarreflective vehicle breakdown warning sign that a driver may use in caseof a vehicle breakdown to display warning and failure messages withouthaving to get off the vehicle for achieving the effect of preventingcollision of autonomous and human-driven vehicles approaching frombehind and protecting the safety of the driver.

A foregoing radar reflective vehicle breakdown warning sign comprises abody and a projecting lamp, and a remote control for connecting to thebody and the projecting lamp. In an interior of the body is disposed acontrol circuit and a transmission component connected to the controlcircuit. The transmission component is pivotally connected to a vehiclebreakdown warning sign. On the vehicle breakdown warning sign aredisposed radar wave reflecting patches which may reflect the radar wavesemitted by a vehicle with an autonomous driving function, and in aninterior of the projecting lamp is disposed a control circuit and alight emitting component connected to the control circuit. The body andthe projecting lamp are respectively disposed on an inner edge of a reartrunk cover and on an inner edge of a rear trunk. When a vehicle breaksdown, the driver may open its rear trunk without having to get off thevehicle, turn on the transmission component to sway the vehiclebreakdown warning sign, and turn on the projecting lamp to illuminatethe vehicle breakdown warning sign and the radar wave reflecting patchesfor facilitating detection by vehicles approaching from behind toachieve the purpose of alerting them and avoiding collision.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer both to FIG. 1 and FIG. 2 , along with FIG. 3 , showingrespectively a three-dimensional view, a three-dimensional explodedview, and a block diagram of the present invention. As the figures show,the present invention comprises a body 1, a vehicle breakdown warningsign 2, a projecting lamp 3, and a remote control 4 for connecting tothe body 1 and projecting lamp 3. In an interior of the body 1 isdisposed a control circuit 11 and a transmission component 12 connectedto the control circuit. A transmission shaft 121 of the transmissioncomponent 12 protrudes from the body 1. In the present embodiment, thetransmission component 12 is a motor.

The vehicle breakdown warning sign 2 is pivotally connected to thetransmission shaft 121 of the transmission component 12. On a surface ofthe vehicle breakdown warning sign 2 are disposed a plurality of concaveand convex radar wave reflecting patches 21, and at a periphery of thevehicle breakdown warning sign 2 is disposed a wall 22 of an appropriateheight.

In an interior of the projecting lamp 3 is disposed a control circuit 31and a light emitting component 32 connected to the control circuit. Inthe present embodiment, the light emitting component 32 is a highbrightness LED.

The remote control 4 provides connection to the control circuits 11 and31 of the body 1 and the projecting lamp 3 so that the transmissioncomponent 12 and light emitting component 32 may be turned on and offvia the control circuits 11 and 31. In the present embodiment, signalsare transmitted between the remote control 4 and the control circuits 11and 31 via Bluetooth or wireless high frequency.

The foregoing components are combined to form a radar reflective vehiclebreakdown warning sign. The body 1 and projecting lamp 3 arerespectively disposed on an inner edge of a rear trunk cover and on aninner edge of a rear trunk. When a vehicle breaks down, the driver mayopen its rear trunk without having to get off the vehicle, turn on thetransmission component 12 in the body 1 to sway the vehicle breakdownwarning sign 2, and turn on the projecting lamp 3 to illuminate thevehicle breakdown warning sign 2 via the light emitting component 32,and further, the radar wave reflecting patches 21 may effectivelyreflect radar waves for facilitating detection by vehicles approachingfrom behind to achieve the purpose of alerting them and avoidingcollision.

Please refer both to FIG. 4 and FIG. 5 , which are drawings of thepresent invention when installed on a vehicle. As the figures show, whenthe present invention is being used, a trunk cover 52 of a rear trunk 51of a vehicle 5 is opened, the body 1 is retained on an inner edge of thetrunk cover 52, and the projecting lamp 3 is disposed on an inner edgeof the rear trunk 51 with the projecting lamp 3 having a lightprojection range in correspondence with the vehicle breakdown warningsign 2 on the body 1. When the present invention is not being used, thetrunk cover 52 is closed to hide the body 1, the vehicle breakdownwarning sign 2 and the projecting lamp 3 in the rear trunk 51.

Please refer to FIG. 6 , showing a drawing of the present invention whenbeing used. Please also refer to FIGS. 1 to 3 . As the figures show,when a vehicle 5 breaks down on the road, the driver may slowly drivethe vehicle 5 to park on a side of the road. After making sure it'ssafe, the driver may open the trunk cover 52 of the rear trunk 51without having to get off the vehicle 5 to display the vehicle breakdownwarning sign 2 on the trunk cover 52 so that vehicles approaching frombehind may see the vehicle breakdown warning sign 2 clearly from afarand may promptly react to avoid accidents.

After opening the trunk cover 52, the driver may control the body 1 andprojecting lamp 3 via the remote control 4 and turn on the transmissioncomponent 12 via the control circuit 11 to sway the vehicle breakdownwarning sign 2 and turn on the light emitting component 32 of theprojecting lamp 3 via the control circuit 31 to project light on thevehicle breakdown warning sign 2, causing the radar wave reflectingpatches 21 to provide a light reflection effect. When a vehicle equippedwith a radar detecting device approaches from behind, the radar is sureto detect the swaying vehicle breakdown warning sign 2, effectivelyprotecting the driver particularly at night when vision is impaired.Further, the radar wave reflecting patches 21 disposed on the vehiclebreakdown warning sign 2 may surely reflect the radar waves emitted fromthe vehicle approaching from behind to even better protect the driver.
